如果想形成互补的话，可以把SpringBoot版本改为2.0之前

然后进行打包，命令台使用–spring.config.location=文件路径

SpringBoot指定日志文件和日志Profile功能失效编写logback-spring.xml文件，使用日志Profile功能。发现控制台中所有配置并未按配置生效

通过Spring Boot 全局配置文件与@Value 取赋值详解与 @ConfigurationProperties 对比已经知道使用“@Value”注解与“@ConfigurationProperties”可以从全局配置文件“application.properties”或者“application.yml”中取值然后为需要的属性赋值

但是如果应用比较大的时候，如果所有的内容都当在一个文件中，如“application.properties”或者“application.yml”中时，就会显得比较臃肿，同时也不太好理解和维护

可以将一个文件拆分为多个，此时使用@PropertySource即可解决问题

@PropertySource 用于加载指定的配置文件

如果说，我们专门编写了一个javaBean来和配置文件进行映射，我们就直接使用@ConfigurationProperties；

person.firstName：使用标准方式
